In the light of Mr William Mitchell's interview with KOMO TV in November 2019, I wonder whether Mr Mitchell would be amenable to enquiries relating to his testimony in 1971 to the FBI and in 2013 to the Washington State Historical Society, with appropriate respect for his privacy.
To this end, is there anyone on this forum who knows (and is willing to share) Mr Mitchell's middle initial (the initial mentioned in Geoffrey Gray's book may not be correct), and his zip code? thus permitting an enquiry by snail mail, to which he would be free to respond, or not.
